Rough guess is that to do some real damage with O2 or the bottles it comes in, you would have to REALLY lucky. The flow rate might be enough to do some damage, but in order to really threaten the aircraft, you would have to be doing weird things for so long and in such an obvious fashion you would end up explaining for the rest of the flight, to both cabin crew and other pax, that you are not a threat to the aircraft.
Personally, I recon the FAA and NWA have considered the carriage and location of supplemental oxygen and it is there because it poses very little risk but is optimally placed for when it is required.
